Graphite has good chemical stability. Through special processing, graphite has characteristics of corrosive resistant, good thermal conductivity, low penetration, etc. It is widely used in manufacturing heat exchangers, condensors, heaters, filters, pump equipment, burning tower, etc. Besides, also used in petroleum, chemical, hydrometallurgy, acid-alkali production, synthetic fiber, paper and other industrial sectors, can save a lot of metal.
For die casting, foundry, and the high temperature metallurgical materials: due to the small thermal expansion coefficient of graphite, and changes in the ability to thermal shock and can be used as moulds for glass, graphite black metal to be cast after the precise size, smooth surface and high yield, can be used without processing or wait for processing, thus saving a large amount of metal.
Graphite also can avoid scaling inside the boilers and can be used as pencil core, pigment, polishing agent. After special processing, graphite can be made to various material used in related industry sectors.
What’s more, graphite is also polishing paste and antirust agent of glass and papermaking industry. It is a necessary material for manufacturing pencils, ink, black paint, printing ink and artifical diamond. It is a good environmental protection material. In America, graphite is used as car battery.
